I am allergic to mold seriously bad. My office has mold problem. It is a fab paying job . Any suggestions?

Any suggestions on dealing with my allergy while at work? We find black mold on floors and walls, we clean it and it comes back. I fight sinus infections every two months and it is directly related to the drainage from allergies. I already take tons of prescribed allergy stuff. What would you do? I can not get an equal job in my city for the pay. Help me work this out, Please!
